DETAILED DESCRIPTION

This disclosure describes wireless communication techniques, protocols,methods, and devices applicable to a docking system environment in whicha wireless dockee (WD), such as a mobile device, may dock wirelesslywith a wireless docking center (WDC), also known as a docking host ordocking station. The WD and WDC may establish a docking session witheach other. The WDC may enable interaction between the WD and any numberof peripheral devices (PF) that are associated with the WDC. Forexample, the peripherals may include displays, projectors, speakers,keyboards, mice, joysticks, data storage devices, network interfacedevices, other docking hosts, remote controls, cameras, microphones,printers, or other devices. Such peripheral devices may includestand-alone devices or components of devices such as other computers, indifferent examples. A user may wirelessly dock a WD, such as a mobilehandset, with a WDC, and enable interaction between the WD and any ofthe peripherals. The WD may be enabled to control aspects of the dockingsession, and to store certain information from one docking session touse in future docking sessions, obviating the need to repeat exchangesof the same information to set up future docking sessions, in someexamples.

In general, wireless docking may be comprised of four components:discovery, connection setup, session setup, and configuration andcontrol protocol. Discovery may enable a WD to identify a WDC and itsservice attributes. After initial discovery, the WD may connect to theWDC by setting up a new ASP session for the docking service. After thesession setup, the configuration and control protocol may enable the WDto negotiate and configure its own use of PFs at the WDC. Subsequently,the WDC may enable the access to the PF services for the WD byestablishing payload connections for individual PF services with the WD.

In some examples, a WD may wirelessly dock with a WDC by selecting oneor more of the PFs associated with the WDC. For instance, WD 4 mayindividually select a display PF and a keyboard PF. In some examples, asopposed to selecting individual PFs, a WD may select one or morewireless docking environments (WDNs) that each correspond to one or moreof the PFs associated with the WDC. In some examples, WDNs may be eitherWD-Centric or WDN-Centric. A WD-Centric WDN is a WDN that is defined(e.g., created) by a WD for use by the WD. Configuration data forWD-Centric WDNs may be stored at WDC, at a WD, or both. A WDC-CentricWDN is a WDN that is available for general use (e.g., by a plurality ofWDs). In some examples, a WDN may be a particular type of WDN. Someexample WDN types include, but are not limited to, an office WDN type,an entertainment WDN type, a public workplace WDN type, an audio onlyWDN type, and an enterprise office WDN type. In some examples, an officeWDN type may be associated with a display PF, a mouse PF, and a keyboardPF. In some examples, an audio only WDN type may be associated with anaudio sink PF (e.g., speakers).

FIG. 1 is a conceptual diagram of an example wireless dockingenvironment (WDE) in which a wireless dockee (WD) is configured towirelessly dock with a wireless docking center (WDC) over a wirelesscommunication channel in order to utilize one or more peripheralsassociated with the WDC, in accordance with one or more techniques ofthis disclosure. As illustrated in FIG. 1, WDE 2 includes WD 4, WDC 6,wireless communication channel 8, peripherals (PF) 10A-10N (collectively“PFs 10”), and communication channels 12A-12N (collectively“communication channels 12”).

WDE 2 may include WD 4 which may be configured to wirelessly dock with aWDC over a wireless communication channel in order to access one or morePFs associated with the WDC. For instance, WD 4 may wirelessly dock withWDC 6 over wireless communication channel 8 in order to access one ormore of PFs 10. Examples of WD 4 may include, but are not limited tomobile devices such as smartphones or other mobile handsets, tabletcomputers, laptop computers, one or more processing units or otherintegrated circuits or chip sets, or other electronic device.

Wireless communication channel 8 may be any channel capable ofpropagating communicative signals between WD 4 and WDC 6. In someexamples, wireless communication channel 8 may be implemented in radiofrequency communications in frequency bands such as the 2.4 gigahertz(GHz) band, the 5 GHz band, the 60 GHz band, or other frequency bands.In some examples, wireless communication channel 8 may comply with oneor more sets of standards, protocols, or technologies among Wi-Fi (aspromoted by the Wi-Fi Alliance), WiGig (as promoted by the WirelessGigabit Alliance), and/or the Institute of Electrical and ElectronicsEngineers (IEEE) 802.11 set of standards (e.g., 802.11, 802.11a,802.11b, 802.11g, 802.11n, 802.11ac, 802.11ad, etc.), or otherstandards, protocols, or technologies. The frequency bands used, such asthe 2.4 GHz, 5 GHz, and 60 GHz bands, may be defined for purposes ofthis disclosure as they are understood in light of the standards ofWi-Fi, WiGig, any one or more IEEE 802.11 protocols, or other applicablestandards or protocols.

WDE 2 may include WDC 6 which may be configured to operate as a wirelessdocking host device for a WD in order to facilitate the WD's utilizationof one or more PFs associated with WDC 6. In other words, WDC 4 may be awireless docking host device that serves as a connectivity agent withina computing and/or communication environment. For instance, WDC 6 maywirelessly dock with WD 4 over wireless communication channel 8 in orderto facilitate WD 4's utilization of one or more of peripherals 10. WDC 6may be a dedicated wireless dock, or may also be implemented in asmartphone or other mobile handset, a tablet computer, a laptopcomputer, a computer monitor, or other electronic device, or as acomponent or subsystem of any of the above.

In some examples, WDC 6 may be associated with one or more of PFs 10. Asone example, a PF of PFs 10 may be associated with WDC 6 where the PF ismanaged by WDC 6. A PF may be considered to be managed by WDC 6 whereWDC 6 is able to facilitate a WD's utilization of the PF. As anotherexample, a PF of PFs 10 may be associated with WDC 6 where the PF iscommunicatively coupled to WDC 6, such as by a respective communicationchannel of communication channels 12.

WDE 2 may include one or more PFs 10 which may be associated with a WDCand may each be configured to provide one or more services to a WD thatis wirelessly docked with the associated WDC. For instance, where a PFof PFs 10 is associated with WDC 6 and WD 4 is wirelessly docked withWDC 6, the PF may provide one or more services to WD 4. Examples of PFs10 may include, but are not limited to, displays, projectors, speakers,keyboards, mice, joysticks, data storage devices, network interfacedevices, other docking hosts, remote controls, cameras, microphones,printers, or any of various other devices capable of providing aservice.

In some examples, one or more of PFs 10 may be communicatively coupledto WDC 6, such as by a respective communication channel of communicationchannels 12. For instance, PF 10A may be communicatively coupled to WDC6 via communication channel 12A. In some examples, one or more ofcommunication channels 12 may be wired communication channels. Forinstance, one or more of communication channels 12 may include auniversal serial bus (USB) cable, a network cable, a fiber optic cable,and/or any other cable capable of communicating information. In someexamples, one or more of communication channels 12 may be wirelesscommunication channels. For instance, one or more of communicationchannels 12 may include a Bluetooth link, a Wi-Fi link (which may besimilar to wireless communication channel 8), an optical link, and thelike. In some examples, one of more of PFs 10 may be included in WDC 6.For instance, WDC 6 may include a display of PFs 6.

A user of WD 4 may desire to access one or more of PFs 10 associatedwith WDC 6 without physically connecting WD 4 to WDC 6. For instance,where WD 4 is a mobile computing device with a relatively smalltouch-sensitive display for receiving user input (e.g., a virtualkeyboard) and PFs 10 include a full size monitor (e.g., 20″ diagonal)and a full size physical keyboard, the user of WD 4 may desire toutilize the full size monitor and the full size keyboard to interactwith WD 4. However, it may not be desirable to require the user toestablish a wired connection between WD 4 and the full size monitor andkeyboard. In accordance with one or more techniques of this disclosure,WD 4 may wirelessly dock with WDC 6 via wireless communication link 8 inorder to access one or more of PFs 10. In this way, techniques of thedisclosure may enable the user to access one or more of PFs 10associated with WDC 6 (i.e., the full size monitor and keyboard) withoutphysically connecting WD 4 to WDC 6.

FIG. 2 is a communication flow diagram illustrating example data flow200 between a WD and a WDC performing techniques to wirelessly dock suchthat the WD may access one or more PFs associated with the WDC, inaccordance with one or more examples of this disclosure. The techniquesof FIG. 2 may be performed by a WD and a WDC, such as WD 4 and WDC 6illustrated in FIG. 1. For purposes of illustration, the techniques ofFIG. 2 are described within the context of WD 4 and WDC 6 of FIG. 1,although computing devices having configurations different than that ofWD 4 and WDC 6 may perform the techniques of FIG. 2.

A docking configuration and control protocol may be used by WD 4 toselect and configure the PFs of its interests in the Docking session.Before the docking configuration and control protocol operates onindividual PFs, WD 4 may perform a user type authentication procedure,if this is required by WDC 6. WDC 6 may indicate such a requirementusing the element “is UserTypeAuthRequired” during a pre-associationdiscovery phase.

An example sequence of the docking configuration and control proceduresfor PFs is shown in FIG. 2. In the example, WD 4 first obtains the PFinformation using the PF Query procedure. Then if needed, WD 4 selectsand configures the PFs of its interests. Upon the completion of the PFselection and configuration, WD 4 and WDC 6 setup the individual PFServices.

FIG. 5 is a communication flow diagram illustrating an example data flowbetween a WD and a WDC performing techniques to wirelessly dock, inaccordance with one or more examples of this disclosure. The techniquesof FIG. 5 may be performed by a WD and a WDC, such as WD 4 and WDC 6illustrated in FIG. 1 and FIG. 4. For purposes of illustration, thetechniques of FIG. 5 are described within the context of WD 4 and WDC 6of FIG. 1 and FIG. 4, although computing devices having configurationsdifferent than that of WD 4 and WDC 6 may perform the techniques of FIG.5. FIGS. 5A-5D each illustrate one or more portions of the example dataflow of FIG. 5 during various phases of an example wireless dockingprocedure. Specifically, FIG. 5A illustrates docking pre-associationdiscovery, FIG. 5B illustrates connection setup, FIG. 5C illustrates ASPsession setup, and FIG. 5D illustrates configuration and control, PFservice session, and teardown.

A user of WD 4 may desire to access one or more of PFs 10 associatedwith WDC 6 without physically connecting WD 4 to WDC 6. For instance,where WD 4 is a mobile computing device with a relatively smalltouch-sensitive display for receiving user input (e.g., a virtualkeyboard) and PFs 10 include a full size monitor (e.g., 20″ diagonal)and a full size physical keyboard, the user of WD 4 may desire toutilize the full size monitor and the full size keyboard to interactwith WD 4. However, it may not be desirable to require the user toestablish a wired connection between WD 4 and the full size monitor andkeyboard. In accordance with one or more techniques of this disclosure,WD 4 may wirelessly dock with WDC 6 via wireless communication link 8 inorder to access one or more of PFs 10. In this way, techniques of thedisclosure may enable the user to access one or more of PFs 10associated with WDC 6 (i.e., the full size monitor and keyboard) withoutphysically connecting WD 4 to WDC 6.

As illustrated in FIG. 5, the docking services (i.e., WDM 36 and WDM 76)may use the ASP to perform the pre-association device and servicediscovery (510). If the docking service provided by WDC 6 matches theinterests of WD 6, the docking service on WDC 6 and the docking serviceon WD 4 may use the ASP to perform a P2P provision discovery procedureand subsequently form a P2P group that includes WDC 6 and the WD 4(520). An ASP Session may then be created for the Docking sessionbetween WDC 6 and WD 4 (530).

Once the ASP session for the docking services is set up, a dockingconfiguration and control protocol may run over the connection of thedocking ASP session (540). The docking configuration and controlprotocol may be used for post-association PF/WDN discovery, PF/WDNselection and configuration for PF Services. In some examples, beforethe PF/WDN selection and configuration is completed, the Docking Servicemay block WD's access to all its PF services.

Upon the completion of the PF/WDN selection and configuration, thedocking service at WDC 6 may allow WD 4 to access those services thatWDC 6 has agreed to offer (550). WD 4 and WDC 6 may perform a PF servicesetup procedure. The PF service setup procedure may in turn includepotential PF connection setup, and PF ASP Session setup.

WD 4 may undock from WDC 6. For instance, a docking session teardownprocedure may be triggered which may cause the docking services to closethe ASP session of each individual PF Service between WDC 6 and WD 4.

As illustrated in FIG. 5A, during docking pre-association discoveryphase 510, WD 4 may perform docking pre-association discovery todetermine one or more PFs associated with WDC 6. For instance, discoverymodule 80 may advertise a wireless docking service of WDC 6 (e.g., WDM76) such that the wireless docking service can be discovered by one ormore WDs. In some examples, discovery module 80 may advertise thewireless docking service by causing ASP module 94 to perform anAdvertiseService method. Discovery module 80 may cause ASP module 94 toperform the AdvertiseService method by specifying one or more of thefollowing parameters: a service name value, an auto-accept value, aservice information value, and/or a service status value. In someexamples, a primitive for the AdvertiseService method may be:AdvertiseService(service_name, auto_accept, service_information,service_status). In some examples, discovery module 80 may specify theservice name value as org.wi-fi.wfds.docking wdc. In some examples,discovery module 80 may specify the service information value asincluding information regarding one or more of PFs 10 and/or one or moreWDNs currently configured at WDC 6. In some examples, discovery module80 may specify the service information value as identifying a dockingenvironment type (DET), such as by using a wdnType element as describedbelow. In some examples, discovery module 80 may specify the serviceinformation value as a UTF-8 text string of XML data that may includethe element preassociationServiceDiscovery. An examplepreassociationServiceDiscovery element which may be defined as providedin the XML schema below.

In some examples, WDC 6 may perform pre-association discovery by sendinga message to WD 4 that indicates that WDC 6 is hosting a wirelessdocking service. In some examples, the message further indicates whetheror not WDC 6 requests performance of a user type authenticationprocedure. In some examples, discovery module 80 may cause ASP module 94to send the message by calling the AdvertiseService method. In someexamples, ASP module 94 may perform the AdvertiseService method bywaiting to receive, from WD 4, a request querying whether or not WDC 6is hosting a wireless docking service.

Discovery module 40 of WD 4 may perform docking pre-associationdiscovery. For instance, discovery module 40 may seek a wireless dockingservice. In some examples, discovery module 40 may seek the wirelessdocking service by causing ASP module 54 to perform a SeekServicemethod. Discovery module 40 may cause ASP module 54 to perform theSeekService method by specifying one or more of the followingparameters: a service name value, an exact search value, a MAC addressvalue, and/or a service information request value. In some examples, aprimitive for the SeekService method may be SeekService(service_name,exact_search, mac_address, service_information_request). In someexamples, discovery module 40 may specify the service name value asorg.wi-fi.wfds.docking.wdc. In some examples, discovery module 40 mayspecify the exact search value as TRUE (or a logical equivalent). Insome examples, discovery module 40 may specify the service informationrequest value as NULL (or a logical equivalent). In some examples,discovery module 40 may specify the service information request value asa particular DET.

ASP module 54 may perform the SeekService method by sending a request toWDC 6 that indicates that WD 4 is seeking a wireless docking service.For instance, ASP module 54 may send a P2P probe request to WDC 6 thatincludes a hash value of the service name value specified by discoverymodule 40 (e.g., org.wi-fi.wfds.docking wdc). In some examples, ASPmodule 54 may send the P2P probe request to WDC 6 via communication unit24.

ASP module 94 may receive the request indicating that WD 4 is seeking awireless docking service. For example, ASP module 94 may receive the P2Pprobe request that includes a hash value of the service name valuespecified by discovery module 40 (e.g., org.wi-fi.wfds.docking.wdc). ASPmodule 94 may match the hash value included in the request to a hashvalue of the service name value specified by discovery module 80 in itsAdvertiseService method call. Responsive to determining that the servicename value specified by discovery module 80 matches the service namevalue specified by discovery module 40 (i.e., that the hash valuesmatch), ASP module 94 may send a P2P probe response to WD 4 thatindicates the service name value specified by discovery module 80 and anadvertisement identifier corresponding to the service name value.

ASP module 54 may receive the response indicating that WDC 6 is hostinga wireless docking service. For example, ASP module 54 may receive theP2P probe response that includes the service name value specified bydiscovery module 80 and the advertisement identifier corresponding tothe service name value. ASP module 54 may then send a P2P servicediscovery request to WDC 6 to request information regarding the PFsassociated with the wireless docking service of WDC 6.

ASP module 94 may receive the request for information regarding the PFsassociated with the wireless docking service of WDC 6. For example, ASPmodule 94 may receive the P2P service discovery request. Responsive toreceiving the request, ASP module 94 may send a response to WD 4 thatincludes information regarding the PFs associated with the wirelessdocking service of WDC 6. For example, ASP module 94 may send a P2Pservice discovery response to WD 4 that includes the informationregarding the PFs associated with the wireless docking service of WDC 6,such as some or all of the information specified by discovery module 80in the service information value when calling the AdvertiseServicemethod and/or advertisement identifiers for the PFs indicated by theservice information. In some examples, the response may includeinformation regarding one or more WDNs configured on WDC 6. In suchexamples, ASP module 94 may receive the information regarding the one ormore WDNs configured on WDC 6 from WDN module 86.

ASP module 54 may receive the response that includes the informationregarding the PFs associated with the wireless docking service of WDC 6.For example, ASP module 54 may receive the P2P service discoveryresponse that includes the information regarding the PFs associated withthe wireless docking service of WDC 6, such as some or all of theinformation specified by discovery module 80 in the service informationvalue when calling the AdvertiseService method. In some examples, ASPmodule 54 may send some or all of the received information to discoverymodule 40. In other words, ASP module 54 may report the results of theSeekService method to discovery module 40, such as with a SearchResultevent. In some examples, the results reported with the SearchResultevent may include a MAC address of WDC 6 and an advertisement identifiercorresponding to the wireless docking service of WDC 6.

Discovery module 40 may then determine whether or not the dockingservice hosted by WDC 6 matches the interests of WD 4. For instance,discovery module may determine whether or not one or more of the PFsincluded in the response from WDC 6 match one or more PFs sought by WD4. In some examples, discovery module 40 may determine the one or morePFs sought by WD 4 by causing UI module 32 to output a GUI requestinguser input to identify the one or more PFs sought by WD 4. In someexamples, the GUI may include one of more of the PFs included in theresponse from WDC 6. In some examples, the GUI may include one or moreof the WDNs included in the response from WDC 6. In some examples,discovery module 40 may determine the one or more PFs sought by WD 4prior to calling the SeekService Method. In any case, responsive todetermine that one or more of the PFs included in the response from WDC6 match one or more of the PFs sought by WD 4, discovery module 40 maysend a signal to setup module 42 requesting establishment of a dockingsession. In this way, discovery module 40 and discovery module 80 mayperform pre-association discovery.

As illustrated by FIG. 5B, during docking connection setup phase 520,setup module 42 and setup module 82 may establish a docking sessionbetween WD 4 and WDC 6. In some examples, setup module 42 and setupmodule 82 may establish the docking session via a direct wirelessconnection between WD 4 and WDC 6. In some examples, setup module 42 andsetup module 82 may setup the direct wireless connection between WD 4and WDC 6 by forming a new P2P group that includes both WD 4 and WDC 6.In some examples, as opposed to creating a new P2P group, setup module42 and setup module 82 may cause WD 4 and WDC 6 to join an existing P2Pgroup. In some examples, the P2P group may be a Wi-Fi Direct P2P group.In some examples, WD 4 may be the group owner. In some examples, WDC 6may be the group owner. In some examples, WD 4 and WDC 6 may performgroup owner negotiation.

In some examples, setup module 42 may setup the P2P group by causing ASPmodule 54 to perform a ConnectSessions method. Setup module 42 may causeASP module 54 to perform the ConnectSessions method by specifying one ormore of the following parameters: a service MAC value, an advertisementidentification value, a session information value, and a network rolevalue. In some examples, a primitive for the ConnectSessions method maybe: ConnectSessions(List of(service_mac, advertisement_id),session_information, network_role). In some examples, setup module 42may specify the service MAC value and the advertisement identificationvalue as the as the MAC address and the advertisement identifiercorresponding to the wireless docking service of WDC 6. As discussedabove, the MAC address and the advertisement identifier corresponding tothe wireless docking service of WDC 6 may be reported to WDM 36 from WDC6 via ASP module 54 in a prior SearchResult event. In some examples,setup module 42 may cause WD 4 to be the group owner by specifying thenetwork role value as 1.

In some examples, ASP module 54 may perform the ConnectSessions methodby exchanging one or more messages with ASP module 94 and notifyingsetup module 42 of one or more events. As one example, ASP module 54 mayperform a SessionStatus event to notify setup module 42 that the sessionhas been initiated. In some examples, ASP module 54 may generate asession identifier for the requested session and provide the sessionidentifier to setup module 42. As another example, ASP module 54 maysend a P2P provision discovery request message to ASP module 94. In someexamples, the P2P provision discovery request message may include thesession identifier. In some examples, the P2P provision discoveryrequest message may include an indication of the connection capabilitiesof WD 4. Some example connection capabilities may include, but are notlimited to, whether the requester (i.e., WD 4) can become a group ownerof a new group, whether the requester can become a client, whether therequester can create a new group, whether the requester has an existinggroup that may be joined by the responder (i.e., WDC 6), etc.

ASP module 94 may receive the P2P provision discovery request messageand, in response, perform a SessionStatus event to notify setup module82 that a session has been requested. In some examples, ASP module 94may perform a ConnectStatus event to notify setup module 82 that asession request has been received from WD 4. In some examples, ASPmodule 94 may accept the session request without further input, such aswhere discovery module 80 specified the auto-accept value as TRUE whencalling the AdvertiseService method. In some examples, ASP module 94 mayseek additional input prior to accepting or denying the session request,such as where discovery module 80 specified the auto-accept value asFALSE when calling the AdvertiseService method.

Where ASP module 94 does not seek additional input, ASP module 94 maynotify ASP module 54 that the session request has been accepted. Forinstance, ASP module 94 may send a P2P provision discovery response toASP 54 that indicates that the session has been accepted. In someexamples, the P2P provision discovery response may include an indicationof one of the connection capabilities of WD 4 (e.g., one or more of theexample connection capabilities described above) that is compatible withthe connection capabilities of WDC 6. ASP module 94 and ASP module 54may then complete group formation and/or joinder. For instance, wherethe connection capabilities of WD 4 are such that WD 4 may create andbecome the owner of a new group and the connection capabilities of WDC 6are such that WDC 6 may join a new group, ASP module 54 may cause WD 4to create the new group and ASP module 94 may cause WDC 6 to join thenew group created by WD 4. In this way, a P2P group may be establishedvia a direct wireless connection between WD 4 and WDC 6.

Where ASP module 94 seeks additional input, ASP module 94 may exchangeinformation with setup module 82 in order to obtain said additionalinput. As one example, ASP module 94 may perform a ConnectStatus eventto notify setup module 82 that the session request received from WD 4has been deferred. As another example, ASP module 94 may perform aSessionRequest event to request instruction from setup module 82 as towhether ASP module 94 should accept or reject the session request.Additionally, in some examples, ASP module 94 may notify ASP module 54that it is seeking additional input. As one example, ASP module 94 maysend a P2P provision discovery response message to ASP module 54 thatindicates that the session request has not yet been accepted (e.g., aP2P provision discovery response message with status(1)).

Setup module 82 may receive the request for instruction and attempt tosolicit user input that indicates whether ASP module 94 should accept orreject the session request. As one example, setup module 82 may cause UImodule 72 to output a request for a user of WDC 6 to provide inputindicating whether ASP module 94 should accept or reject the sessionrequest. For instance, UI module 72 may cause a light of UI devices 66to blink, a prompt to appear on a display of UI devices 66, and thelike. UI module 72 may then receive user input, such as a button press,that indicates that ASP module 94 should accept the session request.Setup module 82 may provide the requested instruction to ASP module 94,such as by calling a ConfirmSession method. Setup module 82 may call theConfirmSession method by specifying one or more of the followingparameters: a session MAC value, a session ID value, and a confirmedvalue. Setup module 82 may specify the session MAC value as the MAC ofWD 4 and the session ID value as the session identifier generated by ASPmodule 54. Setup module 82 may instruct ASP module 94 to accept thesession request by specifying the confirmed value as TRUE. Setup module82 may instruct ASP module 94 to reject the session request byspecifying the confirmed value as FALSE.

ASP module 94 may perform the ConfirmSession method by sending amessage, such as a P2P Provision discovery request message, to ASPmodule 54 that indicates whether or not ASP module 94 accepts thesession request. In some examples, the message may also include sessioninformation. In some examples, ASP module 94 may perform a ConnectStatusevent to notify setup module 82 that the session request has beenaccepted.

ASP module 54 may receive the message and notify setup module 42 whetheror not the session request was accepted. For instance, ASP module 54 mayperform a ConnectStatus event to notify setup module 42 whether or notthe session request was accepted. Where the message indicates that thesession request was accepted, ASP module 54 may begin P2P groupformation. For instance, ASP module 54 may send a message, such as a P2Pprovision discovery response message, to ASP module 94 that includes anindication of one of the connection capabilities of WD 4 (e.g., one ormore of the example connection capabilities described above) that iscompatible with the connection capabilities of WDC 6. In some examples,ASP module 54 may perform a ConnectStatus event to notify setup module42 that group formation has started. ASP module 94 and ASP module 54 maythen complete group formation and/or joinder. For instance, where theconnection capabilities of WD 4 are such that WD 4 may create and becomethe owner of a new group and the connection capabilities of WDC 6 aresuch that WDC 6 may join a new group, ASP module 54 may cause WD 4 tocreate the new group and ASP module 94 may cause WDC 6 to join the newgroup created by WD 4. When ASP module 54 determines that WD 4 and WDC 6are both in the same P2P group, ASP module 54 may perform aConnectStatus event to notify setup module 42 that group formation iscomplete. Similarly, when ASP module 94 determines that WD 4 and WDC 6are both in the same P2P group, ASP module 94 may perform aConnectStatus event to notify setup module 82 that group formation iscomplete. In this way, a P2P group may be established via a directwireless connection between WD 4 and WDC 6.

As illustrated by FIG. 5C, during docking ASP session setup phase 530,ASP module 54 and ASP module 94 may setup an ASP session between WDM 36and WDM 76. In some examples, ASP module 54 and ASP module 94 may setupthe ASP session such that session communications are exchanged via theP2P group of which both WD 4 and WDC 6 are members. In some examples,ASP module 54 may perform ASP session setup by sending a message to ASPmodule 94 that includes a request to create the new ASP session. Forinstance, ASP module 54 may send a request session message that includesone or more of: a session MAC value, a session ID value, anadvertisement ID value, and session information.

ASP module 94 may receive the message and may send a message to ASPmodule 54 that includes an acknowledgement that the message wasreceived. ASP module 94 to perform a SetSessionReady method in order tochange the state of the requested ASP session to open. In some examples,setup module 82 may cause ASP module 94 to perform the SetSessionReadymethod in response to ASP module 94 performing the SessionStatus eventto notify setup module 82 that the session has been requested. In anycase, ASP module 94 may send a message to ASP module 54 that indicateswhether or not the session has been added. As one example, ASP module 94may send an added session message to indicate that the session has beenadded. As one example, ASP module 94 may send a rejected session messageto indicate that the session has been rejected. In either case, themessage may include the session MAC value and the session ID value.

Where ASP module 94 indicates that the session is open, ASP module 94may perform a SessionStatus event to notify setup module 82 that ASPsession setup is complete and the ASP session is ready for use. Asdiscussed above, when performing the SessionStatus event, ASP module 94may also indicate the session MAC, and/or the session ID to setup module82.

Setup module 82 may receive the notification and may instruct ASP module94 to allow incoming connections on a particular port. For instance,setup module 82 may call ASP module 94 to perform a BoundPort method byspecifying one or more of the following parameters: a session MAC value,a session ID value, an IP address, a port value, and a protocol number.In some examples, setup module 82 may specify the session MAC value asthe session MAC of the ASP session. In some examples, setup module 82may specify the session ID value as the session ID of the ASP session.In some examples, setup module 82 may specify the session protocol valueas 6 (e.g., TCP).

ASP module 94 may perform one or more operations to allow incomingcommunications on the particular port. For instance ASP module 94 mayperform the BoundPort method by determining whether or not theparticular port specified by setup module 82 is allowed. In someexamples, ASP module 94 may perform a PortStatus event to notify setupmodule 82 as to whether or not the particular port is allowed. If theparticular port is allowed, ASP module 94 may send a message, such as anallowed port message, to ASP module 54 indicating that communications ofthe ASP session should be addressed to the particular port. If theparticular port is not allowed, setup module 82 may specify another portuntil an allowable port is determined.

ASP module 54 may receive the message and may perform a PortStatus eventto notify setup module 42 that communications of the ASP session shouldbe addressed to the particular port. Responsive to receiving the messagefrom ASP module 94 indicating that the session has been added, ASPmodule 54 may perform a SessionStatus event to notify setup module 42that ASP session setup is complete and the ASP session is ready for use.As discussed above, when performing the SessionStatus event, ASP module54 may also indicate the session MAC, and/or the session ID to setupmodule 42.

Setup module 42 may receive the notification and may instruct ASP module54 to allow incoming connections on a particular port. For instance,setup module 42 may call ASP module 54 to perform a BoundPort method byspecifying one or more of the following parameters: a session MAC value,a session ID value, an IP address, a port value, and a protocol number.In some examples, setup module 42 may specify the session MAC value asthe session MAC of the ASP session. In some examples, setup module 42may specify the session ID value as the session ID of the ASP session.In some examples, setup module 42 may specify the session protocol valueas 6 (e.g., TCP).

ASP module 54 may perform one or more operations to allow incomingcommunications on the particular port. For instance ASP module 54 mayperform the BoundPort method by determining whether or not theparticular port specified by setup module 42 is allowed. In someexamples, ASP module 54 may perform a PortStatus event to notify setupmodule 42 as to whether or not the particular port is allowed. If theparticular port is allowed, ASP module 54 may send a message, such as anallowed port message, to ASP module 94 indicating that communications ofthe ASP session should be addressed to the particular port. If theparticular port is not allowed, setup module 42 may specify another portuntil an allowable port is determined. In this way, WDM 36 of WD 4 mayestablish a docking session with WDM 76 of WDC 6 via a direct wirelessconnection. As illustrated by FIG. 5C, an application socket may beconnected between WDM 36 and WDM 76.

As illustrated by FIG. 5D, during docking configuration and controlprotocol phase 540, WD 4 and WDC 6 may perform post-associationdiscovery and configuration. For instance, WDM 36 and/or WDM 76 mayperform one or more of a PF query procedure, a PF selection andconfiguration procedure, a PF list change procedure, a WDN queryprocedure, a WDN selection procedure, a WDN list change procedure, anauthentication procedure, a WDN creation procedure, a WDN modificationprocedure, a WD triggered WDN deletion procedure, and a WDC triggeredWDN deletion procedure. Example details of the procedures are discussedbelow with reference to FIGS. 6A-6K, respectively.

As illustrated by FIG. 5D, during docking PF service session phase 550,WD 4 and WDC 6 may perform session setup for the PF services andexchange PF data. In some examples, WD 4 and/or WDC 6 may performsession setup for the PF services by performing potential PF connectionsetup and/or PF ASP session setup. In some examples, WD 4 and/or WDC 6may perform one or more actions to prepare for session setup. As oneexample, control module 42 may trigger and/or configure one or more ofPF service modules 52 that correspond to the one or more PFs and/or theone or more WDNs selected by WD 4 and accepted by WDC 6. For instance,control module 42 may trigger a particular PF service module of PFservice modules 52 to use a corresponding PF service module of PFservice modules 92. As another example, control module 82 may activateand/or configure one or more of PF service modules 92 that correspond tothe one or more PFs and/or the one or more WDNs selected by WD 4 andaccepted by WDC 6. For instance, control module 82 may configure aparticular PF service module of PF service modules 92 for use by acorresponding PF service module of PF service modules 52.

In some examples, control module 44 may cause ASP module 54 to setup oneor more ASP sessions between one or more of PF service modules 52 andone or more of PF service modules 92. In some examples, control module84 may cause ASP module 94 to setup one or more ASP sessions between oneor more PF service modules of PF service modules 52 and one or morecorresponding PF service modules of PF service modules 92.

In any case, the one or more PF service modules of PF service modules 52may begin to exchange PF data with the one or more corresponding PFservice modules of PF service modules 92. For instance, a displayservice module of PF service modules 52 may begin to send display data(e.g., video data) to a corresponding display service module of PFservice modules 92 which may cause a corresponding display peripheral ofPFs 10 to output the display data. In this way, WD 4 may wirelessly dockwith WDC 6. In some examples, WDC assisted direct pairing between a WDand an External Wi-Fi Capable Peripheral may also be used.

As illustrated by FIG. 5D, during docking ASP session teardown phase560, WD 4 and WDC 6 may perform a session teardown procedure to closeone or more open sessions between WD 4 and WDC 6. In some examples, thesession teardown procedure may be initiated by WD 4. For instance,teardown module 50 may initiate the teardown procedure. In someexamples, the session teardown procedure may be initiated by WDC 6. Forinstance, teardown module 90 may initiate the teardown procedure. Insome examples, WD 4 and/or WDC 6 may perform the session teardownprocedure to close a particular session. For instance, where WD 4 nolonger seeks to use a particular PF, WD 4 may perform the sessionteardown procedure to close the particular session (e.g., an ASPsession) between a particular PF service module of PF service modules 52and a corresponding PF service module of PF service modules 92associated with the particular PF. In some examples, WD 4 and/or WDC 6may perform the session teardown procedure to close every sessionbetween WD 4 and WDC 6. For instance, where WD 4 is undocking from WDC6, WD 4 may perform the session teardown procedure to close everysession between WD 4 and WDC 6.

WD 4 and/or WDC 6 may close a particular session by sending thecorresponding device a message requesting closure of the particularsession. For instance, teardown module 50 may close a particular sessionby calling ASP module 54 to perform a CloseSession method. In someexamples, teardown module 50 may call ASP module 54 to perform aCloseSession method by specifying one or more of the followingparameters: a session MAC value, and a session ID value. In someexamples, setup module 42 may specify the session MAC value as thesession MAC of the particular session. In some examples, setup module 42may specify the session ID value as the session ID of the particularsession. In some example, ASP module 54 may perform the CloseSessionmethod by sending a remove_session message to ASP module 94 thatindicates an identification value that corresponds to the particularsession (e.g., the session MAC of the particular session and/or thesession ID of the particular session). In some examples, ASP module 54may notify WDM 76 that the session has been closed by performingSessionStatus event. In some examples, such as where the particularsession is the ASP session between WDM 36 and WDM 76, ASP module 54 maysend a disassociation message to ASP 94. In some examples, ASP module 54may determine whether or not any other sessions are active on the portused by the particular session. Where ASP module 54 determines that noother sessions are active, ASP module 94 may close the port.

WDC 6 may receive the message requesting closure of the particularsession. For instance, ASP module 94 may receive the remove_sessionmessage. In some examples, in response to receiving the remove_sessionmessage, ASP module 94 may perform SessionStatus event to notify WDM 76that the particular session has been closed. In some examples, ASPmodule 94 may send a message to ASP module 54 to acknowledge receipt ofthe remove_session message. In some examples, ASP module 94 maydetermine whether or not any other sessions are active on the port usedby the particular session. Where ASP module 94 determines that no othersessions are active, ASP module 94 may close the port. In this way, asession between WD 4 and WDC 6 may be torn down.

FIGS. 6A-6K are communication flow diagrams illustrating example dataflows between a WD and a WDC performing various wireless dockingtechniques, in accordance with one or more examples of this disclosure.The techniques of FIGS. 6A-6K may be performed by a WD and a WDC, suchas WD 4 and WDC 6 illustrated in FIG. 1 and FIG. 4. For purposes ofillustration, the techniques of FIGS. 6A-6K are described within thecontext of WD 4 and WDC 6 of FIG. 1 and FIG. 4, although computingdevices having configurations different than that of WD 4 and WDC 6 mayperform the techniques of FIGS. 6A-6K.

FIG. 6A illustrates an example data flow between WD 4 and WDC 6 duringthe performance of an example PF query procedure. As illustrated by FIG.6A, WD 4 may send a PF query request to WDC 6. For instance, controlmodule 44 of WDM 36 of WD 4 may send a message to control module 84 ofWDM 76 of WDC 6 that includes a request for information regarding one ormore PFs associated with WDC 6 (e.g., one or more of PFs 10). In someexamples, the request may include a “pfQueryReq” type XML element whichmay be defined as provided in the XML schema below.

Responsive to receiving the query request from WD 4, WDC 6 may send aquery response. For instance, control module 84 may send a message tocontrol module 44 that includes information regarding the one or morePFs associated with WDC 6. In some examples, the response may include a“pfQueryRsp” type XML element which may be defined as provided in theXML schema below. In some examples, the information may include a listthat identifies the one or more PFs associated with WDC 6. In someexamples, the list may identify every PF associated with WDC 6. In someexamples, the list may identify a subset of the PFs associated with WDC6, such as the PFs that are currently available for access by a WD.

In some examples, the information may also include attributes andfeasible configurations of the one or more PFs associated with WDC 6. Insome examples, control module 84 may indicate the one or more PFsassociated with WDC 6 and the attributes and the feasible configurationsof the one or more PFs associated with WDC 6 by including in theresponse, a respective XML element for each PF associated with WDC 6. Insome examples, each respective XML element may be of typeperipheralFunction which may be defined as provided in the XML schemabelow. In some examples, support of the PF Query procedure may bemandatory on both WD 4 and WDC 6.

FIG. 6B illustrates an example data flow between WD 4 and WDC 6 duringthe performance of an example PF selection and configuration procedure.As illustrated by FIG. 6B, WD 4 may send a PF selection andconfiguration request to WDC 6. For instance, control module 44 of WDM36 of WD 4 may send a message to control module 84 of WDM 76 of WDC 6that includes a request to use one or more of the PFs associated withWDC 6. In some examples, control module 44 may include a“pfSelectionReq” type XML element in the request which may be defined asprovided in the XML schema below. In some examples, control module 44may individually identify one or more PFs to which WD 4 seeks access(e.g., a set of sought PFs) in the request. For instance, control module44 may include a “pfSelection” element for each sought PF, and a“selectionStyle” element set to “specific” in the message. In someexamples, control module 44 may indicate a desired configuration foreach of the sought PFs in the “pfSelection” element. In some examples,control module 44 may indicate selection of a default set of PFsassociated with WDC 6 (i.e., in such examples, control module 44 may notindividually identify the sought PFs). For instance, control module 44may include a “selectionStyle” element set to “all” in the message.

Responsive to receiving the selection request from WD 4, WDC 6 may senda selection response. For instance, control module 44 may send a messageto control module 84 that indicates whether or not the selection requestis accepted. In some examples, the response may include a“pfSelectionRsp” type XML element which may be defined as provided inthe XML schema below.

In some examples, WD 4 may desire to de-select one or more PFsassociated with WDC 6 that are currently selected by WD 4. In suchexamples, WD 4 may perform a de-selection procedure. For instance,control module 44 may send a message to control module 84 that includesa request to de-select one or more of the PFs associated with WDC 6currently selected by WD 4. In some examples, control module 44 mayindividually identify the one or more PFs to which WD 4 seeks tode-select in the request. For instance, control module 44 may include a“pfSelection” element for each de-selected PF, and a “selectionStyle”element set to “specific” in the message. In some examples, controlmodule 44 may indicate de-selection of all PFs associated currentlyselected by WD 4. For instance, control module 44 may include a“selectionStyle” element set to “all” in the message. In such examples,control module 44 may cause teardown module 50 to perform a teardownprocedure.

In other words, WD 4 may use the PF selection and configurationprocedure to select and configure the PFs of its interests, and in someexamples, may be performed after WD 4 has obtained the updated PFinformation. In some examples, support of the PF selection andconfiguration procedure may be mandatory on both WD 4 and WDC 6.However, in some examples, the procedure may allow WD 4 to notexplicitly select or configure PFs individually.

FIG. 6C illustrates an example data flow between WD 4 and WDC 6 duringthe performance of an example PF list change procedure. In someexamples, information regarding the one or more PFs associated with WDC6 may change. As one example, the information regarding the one or morePFs associated with WDC 6 may change where an additional PF becomesassociated with WDC 6 (e.g., an additional PF is plugged in to WDC 6).As another example, the information regarding the one or more PFsassociated with WDC 6 may change where a PF associated with WDC 6becomes available for use (e.g., where another WD has de-selected thePF). In any case, responsive to determining that the informationregarding the one or more PFs associated with WDC 6 has changed (i.e.,where WDC 6 has updated information regarding the one or more PFsassociated with WDC 6), WDC 6 may send a PF change notification to WD 4.In other words, WDC 6 may use PF Change Notification procedure to informWD 4 of PF changes. For instance, control module 84 may send a messageto control module 44 that includes updated information regarding the oneor more PFs associated with WDC 6. In some examples, the updatedinformation may include a list of PFs associated with WDC 6 andattributes and feasible configurations of the listed PFs. In someexamples, the message may include a “pfChangeNotif” type XML elementwhich may be defined as provided in the XML schema below. As shown inFIG. 6C, WD 4 may, responsive to receiving the PF change notification,perform a PF selection and configuration procedure as described above.In other words, the procedure may trigger WD 4 to perform the PFselection and configuration procedure again. In some examples, supportof the PF change notification procedure may be mandatory on both WD 4and WDC 6.

FIG. 6D illustrates an example data flow between WD 4 and WDC 6 duringthe performance of an example WDN query procedure. As illustrated byFIG. 6D, WD 4 may send a WDN query request to WDC 6. For instance, WDNmodule 46 of WDM 36 of WD 4 may send a message to WDN module 86 of WDM76 of WDC 6 that includes a request for information regarding one ormore WDN configured for use on WDC 6. In some examples, the request mayinclude a “wdnQueryReq” type XML element which may be defined asprovided in the XML schema below.

Responsive to receiving the query request from WD 4, WDC 6 may send aquery response. For instance, WDN module 86 may send a message to WDNmodule 46 that includes information regarding the one or more WDNsconfigured for use on WDC 6. In some examples, the response may includea “wdnQueryRsp” type XML element which may be defined as provided in theXML schema below. In some examples, the information may include a listthat identifies the one or more WDNs configured for use on WDC 6. Insome examples, the list may identify every WDN configured for use on WDC6. In some examples, the list may identify a subset of the WDNsconfigured for use on WDC 6, such as the WDNs that are currentlyavailable for access by a WD.

In some examples, the information may also include attributes andfeasible configurations of the one or more WDNs configured for use onWDC 6. In some examples, WDN module 86 may indicate the one or more WDNsconfigured for use on WDC 6 and the attributes and the feasibleconfigurations of the one or more WDNs configured for use on WDC 6 byincluding in the response, a respective XML element for each WDNconfigured for use on WDC 6. In some examples, each respective XMLelement may be of type “wdn” which may be defined as provided in the XMLschema below.

In other words, WD 4 may use the PF Query procedure to obtain the WDNinformation. In some examples, support of the WDN Query procedure may beoptional on both WD 4 and WDC 6. In some examples, WDC 6 may indicatewhether the WDN Query procedure is supported during the pre-associationdiscovery phase.

FIG. 6E illustrates an example data flow between WD 4 and WDC 6 duringthe performance of an example WDN selection procedure. As illustrated byFIG. 6E, WD 4 may send a WDN selection request to WDC 6. For instance,WDN module 46 of WDM 36 of WD 4 may send a message to WDN module 86 ofWDM 76 of WDC 6 that includes a request to use a particular WDN of theone or more WDNs configured for use on WDC 6 to which WD 4 seeks access.In some examples, WDN module 46 may include a “wdnSelectionReq” type XMLelement in the request which may be defined as provided in the XMLschema below. In some examples, WDN module 46 may include an identifierof the particular WDN to which WD 4 seeks access in the message.

Responsive to receiving the selection request from WD 4, WDC 6 may senda selection response. For instance, WDN module 46 may send a message toWDN module 86 that indicates whether or not the selection request isaccepted. In some examples, the response may include a “wdnSelectionRsp”type XML element which may be defined as provided in the XML schemabelow.

In other words, WD 4 may use the WDN Selection procedure to select apre-configured WDN (e.g., a WDN previously created by WD 4) and/or aWD-Centric WDN. In some examples, WD 4 may perform the WDN selectionprocedure after WD 4 has obtained the WDN information. In some examples,support of the WDN Selection procedure may be optional on both WD 4 andWDC 6. In some examples, WDC 6 may indicate whether the WDN Selectionprocedure is supported during the pre-association discovery phase.

In some examples, WD 4 may desire to de-select one or more WDNsconfigured for use on WDC 6 that are currently selected by WD 4. In suchexamples, WD 4 may perform a de-selection procedure. For instance, WDNmodule 46 may send a message to WDN module 86 that includes a request tode-select one or more of the WDNs configured for use on WDC 6 that arecurrently selected by WD 4. In some examples, WDN module 46 mayindividually identify the one or more WDNs that WD 4 seeks to de-selectin the request. For instance, WDN module 46 may include a “wdnSelection”element for each de-selected WDN, and a “selectionStyle” element set to“specific” in the message. In some examples, WDN module 46 may indicatede-selection of all WDNs currently selected by WD 4. For instance, WDNmodule 46 may include a “selectionStyle” element set to “all” in themessage. In such examples, WDN module 46 may cause teardown module 50 toperform a teardown procedure.

FIG. 6F illustrates an example data flow between WD 4 and WDC 6 duringthe performance of an example WDN list change procedure. In someexamples, information regarding the one or more WDNs configured for useon WDC 6 may change. As one example, the information regarding the oneor more WDNs configured for use on WDC 6 may change where one or more ofthe PFs corresponding to a WDN becomes available for use (e.g., whereanother WD has de-selected the PF). As another example, the informationregarding the one or more WDNs configured for use on WDC 6 may changewhere a new WDN is defined (e.g., where a WD has created a new WDN). Inany case, responsive to determining that the information regarding theone or more WDNs configured for use on WDC 6 has changed (i.e., whereWDC 6 has updated information regarding the one or more WDNs configuredfor use on WDC 6), WDC 6 may send a WDN change notification to WD 4. Forinstance, WDN module 86 may send a message to WDN module 46 thatincludes updated information regarding the one or more WDNs configuredfor use on WDC 6. In some examples, the updated information may includea list of WDNs configured for use on WDC 6 and attributes and feasibleconfigurations of the listed WDNs. In some examples, the message mayinclude a “wdnChangeNotif” type XML element which may be defined asprovided in the XML schema below. As shown in FIG. 6F, WD 4 may,responsive to receiving the WDN change notification, perform a WDNselection and configuration procedure as described above.

FIG. 6G illustrates an example data flow between WD 4 and WDC 6 duringthe performance of an example authentication procedure. As illustratedby FIG. 6G, WD 4 may send a user type authentication request to WDC 6.For instance, access control module 48 of WD 4 may send a message toaccess control module 88 of WDC 6 that includes one or more credentialscorresponding to a user of WD 4. In some examples, the one or morecredentials may indicate a user type of the user of WD 4 and/or apassphrase. Some example user types may include, but are not limited to,owner, guest, administrator, child, and parent. In some examples, themessage may include a “userTypeAuthReq” type XML element which may bedefined as provided in the XML schema below. In such examples, accesscontrol module 48 may indicate the user type using the “userType”element and the passphrase using the “passphrase” element.

WDC 6 may receive the user type authentication request and determine oneor more rights associated with the information indicated by the request(e.g., the user type and/or the passphrase). As one example, accesscontrol module 88 may determine whether the information indicated by therequest grants access rights to one or more of PFs 10. Where the usertype is administrator, access control module 88 may determine that theinformation indicated by the request grants access rights to every PF ofPFs 10. Where the user type is guest, access control module 88 maydetermine that the information indicated by the request grants accessrights to a subset of PFs 10. As another example, access control module88 may determine whether the information indicated by the request grantsaccess rights to one or more WDNs configured for use on WDC 6. Asanother example, access control module 88 may determine whether theinformation indicated by the request grants rights create new WDNs foruse on WDC 6. As another example, access control module 88 may determinewhether the information indicated by the request grants rights modifyexisting WDNs configured for use on WDC 6. As another example, accesscontrol module 88 may determine whether the information indicated by therequest grants rights delete existing WDNs configured for use on WDC 6.Where the user type is administrator, access control module 88 maydetermine that the information indicated by the request grants rights todelete any WDN of the one or more WDNs configured for use on WDC 6.Where the user type is guest, access control module 88 may determinethat the information indicated by the request does not grant rights todelete any WDN of the one or more WDNs configured for use on WDC 6.

In other words, WD 4 may use the user type authentication procedure toestablish its access rights (e.g., to PF Services). In some examples,support of the user type authentication procedure may be optional onboth WD 4 and WDC 6. In some examples, WDC 6 may indicate whether theuser type authentication is needed during the pre-association discoveryphase.

FIG. 6H illustrates an example data flow between WD 4 and WDC 6 duringthe performance of an example WDN creation procedure. As illustrated byFIG. 6H, WD 4 may send a WDN create request to WDC 6. For instance, WDNmodule 46 may send a message to WDN module 86 that includes a request tocreate a new WDN for use on WDC 6. In some examples, the request mayinclude an indication of a set of PFs associated with WDC 6 that WD 4 isrequesting to correspond to the new WDN. For instance, WDN module 46 mayrequest that a new WDN be created that corresponds to a particulardisplay PF, a particular audio playback PF, and a particular user inputPF. In some examples, WDN module 46 may indicate the set of PFs byindividually identifying each PF of the set of PFs. For instance, WDNmodule 46 may specify, for each respective PF of the set of PFs, anidentification value that uniquely identifies the respective PF (e.g.,where PF ID2 corresponds to the particular display PF, PF ID 4corresponds to the particular audio playback PF, and PF ID 7 correspondsto the particular user input PF, WDN module 46 may request that a newWDN be created that corresponds to PF ID2, PF ID 4, and PF ID 7). Insome examples, WDN module 46 may indicate the set of PFs by indicatingthat the set of PFs consists of one or more PFs currently being accessedby WD 4. For instance, where WD 4 is currently accessing the particulardisplay PF, the particular audio playback PF, and the particular userinput PF, WDN module 46 may request that a new WDN be created thatcorresponds to the PFs currently being accessed by WD 4.

In some examples, WDN module 46 may include a “wdnCreateReq” type XMLelement in the request which may be defined as provided in the XMLschema below. In some examples, such as when WDN module 46 requests thata new WDN be created that corresponds an identified set of PFs, WDNmodule 46 may specify a selectionStyle element of the wdnCreateReqelement as specific. In some examples, such as when WDN module 46requests that a new WDN be created that corresponds to the PFs currentlybeing accessed by WD 4, WDN module 46 may specify the selectionStyleelement of the wdnCreateReq element as current.

Responsive to receiving the request from WD 4, WDC 6 may determinewhether to accept or reject the request to create the new WDN. As oneexample, WDN module 86 may determine whether to accept or reject therequest to create the new WDN based on whether or not WD 4 is authorizedto create new WDNs. As another example, WDN module 86 may determinewhether to accept or reject the request to create the new WDN based onwhether or not WD 4 is authorized to access the one or more PFsrequested to correspond to the new WDN. In any case, WDC 6 may send aresponse to WD 4 that indicates whether or not the request to create thenew WDN was accepted. For instance, WDN module 86 may send a message toWDN module 46 that indicates whether or not the request to create thenew WDN was accepted. Where the request to create the new WDN wasaccepted, WDN module 86 may include identifying information for the newWDN in the message. In some examples, the message may include a“wdnCreateRsp” type XML element which may be defined as provided in theXML schema below. In some examples, such as where another WD iscurrently docked with WDC 6, WDC 6 may perform a WDN list changeprocedure, such as the example WDN list change procedure described abovewith reference to FIG. 4F, to notify the other WD that the new WDN hasbeen created.

In some examples, configuration information for the new WDN may bestored at WD 4, WDC 6, or both. In some examples, support of theWD-Centric WDN creation procedure may be optional on both WD 4 and WDC6. In some examples, WDC 6 may indicate whether the WD-Centric WDNcreation procedure is supported during the pre-association discoveryphase.

FIG. 6I illustrates an example data flow between WD 4 and WDC 6 duringthe performance of an example WDN modification procedure. As illustratedby FIG. 6I, WD 4 may send a WDN modify request to WDC 6. For instance,WDN module 46 may send a message to WDN module 86 that includes arequest to modify an existing WDN of the one or more WDNs configured foruse on WDC 6. In some examples, the request may include an indication ofthe existing WDN and a set of PFs associated with WDC 6 to which WD 4 isrequesting the existing WDN be modified to correspond. As one example,where the existing WDN corresponds to a particular audio playback PF,and a particular user input PF, WDN module 46 may request that theexisting WDN be modified to additionally correspond to a particulardisplay PF. As another example, where the existing WDN corresponds to aparticular audio playback PF, and a particular user input PF, WDN module46 may request that the existing WDN be modified to no longer correspondto the particular user input PF. In some examples, WDN module 46 mayinclude a “wdnModReq” type XML element in the request which may bedefined as provided in the XML schema below.

Responsive to receiving the request from WD 4, WDC 6 may determinewhether to accept or reject the request to modify the existing WDN. Asone example, WDN module 86 may determine whether to accept or reject therequest to modify the existing WDN based on whether or not WD 4 isauthorized to modify the existing WDN. As another example, WDN module 86may determine whether to accept or reject the request to modify theexisting WDN based on whether or not WD 4 is authorized to access theone or more PFs requested to correspond to the existing WDN. In anycase, WDC 6 may send a response to WD 4 that indicates whether or notthe request to modify the existing WDN was accepted. For instance, WDNmodule 86 may send a message to WDN module 46 that indicates whether ornot the request to modify the existing WDN was accepted. In someexamples, the message may include a “wdnModRsp” type XML element whichmay be defined as provided in the XML schema below. In some examples,such as where another WD is currently docked with WDC 6, WDC 6 mayperform a WDN list change procedure, such as the example WDN list changeprocedure described above with reference to FIG. 4F, to notify the otherWD that the existing WDN has been modified.

In some examples, configuration information for the modified WDN may bestored at WD 4, WDC 6, or both. In some examples, support of theWD-Centric WDN modification procedure may be optional on both WD 4 andWDC 6. In some examples, WDC 6 may indicate whether the WD-Centric WDNmodification procedure is supported during the pre-association discoveryphase.

FIG. 7 is a communication flow diagram illustrating an example data flowbetween a WD and a WDC performing techniques to wirelessly dock, inaccordance with one or more examples of this disclosure. The techniquesof FIG. 7 may be performed by a WD and a WDC, such as WD 4 and WDC 6illustrated in FIG. 1 and FIG. 4. For purposes of illustration, thetechniques of FIG. 7 are described within the context of WD 4 and WDC 6of FIG. 1 and FIG. 4, although computing devices having configurationsdifferent than that of WD 4 and WDC 6 may perform the techniques of FIG.7.

In accordance with one or more techniques of this disclosure, WD 4 andWDC 6 may exchange communications as follows. WD 4 and WDC 6 mayexchange WPS information (1502). For example, the user may push abutton, enter a PIN, or touch an NFC interface. In some examples, WD 4and WDC 6 may exchange the WPS information only during their firstconnection. WD 4 and WDC 6 may then exchange connection setupinformation with WPA2 (1504). In some examples, WD 4 and WDC 6 mayexchange the connection setup information in response to a trigger, suchas triggered WPS or selecting an icon on a UI. WD 4 and WDC 6 may thenexchange ASP session setup information for the docking service (1506).WD 4 may then communicate user type authentication information withinthe docking service to WDC 120 (1508).

WD 4 and WDC 6 may then exchange ASP session setup information and PFData for various PF Services (e.g., PF Services A, B, etc.). Asillustrated in FIG. 7, the user type authentication information maycontrol the admission of ASP session setup for individual PF services(1522), and/or trigger ASP session setup for individual PF services(1524).

In some examples, such as where WD 4 is not allowed to access a certainPF Service, docking as the application from the perspective of itsinterfaced PF Service shall not accept the ASP session setup for thecorresponding PF Service. Upon the completion of the PF Service setup,WD 4 can use the PF Service(s) at WDC 6.

FIG. 9 a conceptual diagram illustrating example wireless dockingarchitecture 900 that may be implemented by a wireless docking device,in accordance with one or more techniques of this disclosure. Examplesof wireless docking devices which may include architecture 900 arewireless dockees (such as WD 4 of FIG. 1 and FIG. 4) and wirelessdocking centers (such as WDC 6 of FIG. 1 and FIG. 4).

As illustrated in FIG. 9, architecture 900 may include communicationslayer 902 (e.g., Wi-Fi Direct/TDLS/Infrastructure/802.11n/ac/ad),application service platform (ASP) 904, docking service 906, printservice 908, wireless display service 910 (e.g., Miracast), Wi-Fi SerialBus (WSB) service 912, and one or more other peripheral services914A-914N (collectively, “peripheral services 914”).

As illustrated in FIG. 9, architecture 900 may define a plurality ofinterfaces through which docking service 906 may manage one or moreother components of architecture 900. For instance, docking service 906may manage ASP events and methods with ASP 904 via interface 916, manageprint service 908 via interface 918, manage wireless display service 910via interface 920, manage WSB 912 via interface 922, and manageperipheral services 914 via interface 944.

Docking service 906 may utilize the interfaces and events provided byASP 904 to perform service discovery and session setup between a WD anda WDC. Where architecture 900 is implemented by a WDC, interface 916between the docking service 906 and ASP 904 may enable docking service906 at the WDC to perform one or more of: advertising docking service906 (including PFs manages by docking service 906 and capabilitiesrequired to drive the use of its peripheral functions), and enable a WDto wirelessly connect to the WDC. Where architecture 900 is implementedby a WD, interface 916 between the docking service 906 and the ASP 904may allow docking service 906 at the WD to perform the one or more of:seeking the docking service 906 at a WDC (including PFs the managed byWDC and capabilities required to drive the use of its PFs), andwirelessly connect to the WDC.

Docking service 906 may include a docking configuration and controlprotocol, which may be used by a WD to configure its docking sessionprovided by a WDC, as described above.

A PF service (e.g., PF services 914) may or may not be deployed directlyon top of ASP 904. Docking service 906 may communicate with the PFServices on the same docking device, serving as a management entity ontop of the PF Services. Where architecture 900 is implemented by a WDC,interface 916 between docking service 906 and PF Services (e.g., print,display and WSB), may allow docking service 906 at the WDC to performone or more of: activate and deactivate a PF service, control the WD'saccess to a PF service at the WDC, and configure the PF Service for aWD's use. Where architecture 900 is implemented by a WD, interface 916between docking service 906 and PF Services (e.g., print, display andWSB), may allow docking service 906 to perform one or more of:triggering a PF service at the WD to seek and use the corresponding PFservice at a WDC, and configuring the PF Service for a WD's use.

In accordance with one or more techniques of this disclosure, WD 4 maydetermine one or more PFs associated with WDC 6 (1100). For example, WD4 may receive a list that indicates the one or more PFs associated withWDC 6.

WD 4 may establish a docking session via a direct wireless connectionbetween WD 4 and WDC 6 (1102). For example, WD 4 may form a P2P groupthat includes WD 4 and WDC 6. As another example, WD 4 may open an ASPsession between a docking service of WD 4 and a corresponding dockingservice of WDC 6.

WD 4 may select at least one PF of the one or more PFs associated withWDC 6 (1104). For example, WD 4 may send a message to WDC 6 requestingaccess to at least one of the one or more PFs associated with WDC 6.

WD 4 may access the at least one PF of the one or more PFs associatedwith WDC 6 (1106). For instance, WD 4 may receive PF data from the atleast one PF of the one or more PFs associated with WDC 6.

In some examples, when performing one or more techniques of thisdisclosure, a WD, such as WD 4 of FIG. 1 and FIG. 4, and/or a WDC, suchas WDC 6 of FIG. 1 and FIG. 4, may call one or more Wi-Fi DirectServices (WFDS) methods. Some example WFDS methods that may be calledare provided below. The parameters of one or more of the methods may bedefined in WFDS Technical Specification, the entirety of which is herebyincorporated by reference. While described as being associated withcertain phases (e.g., discovery, setup, teardown) each of the followingmethods may be called at any point during a wireless docking procedure.

One or more of the following methods may be used during servicediscovery and connection setup.

-   -   Docking SeekService Method        -   Example primitive: SeekService(service_name, exact_search,            mac_address, service_information_request)        -   A WD that seeks for a WDC and calls the SeekService Method            may specify the service_name to be            “org.wi-fi.wfds.docking.wdc” with exact_search set to TRUE.        -   The service_information_request string specified by the WD            may be either NULL or a substring of the service information            text a WDC may provide.    -   Docking AdvertiseService Method        -   Example primitive: AdvertiseService(service_name,            auto_accept, service_information, service_status)        -   A WDC that calls the AdvertiseService Method may specify the            service_name to be “org.wi-fi.wfds.wsb.wdc”.        -   The service_information may be a UTF-8 text string of XML            data that may include the element            “preassociationServiceDiscovery” which may be defined below.        -   The service_information may include information of PFs and            pre-configured WDNs.        -   The service_information may identify the Docking Environment            Type (DET) using the element “wdnType”.

One or more of the following methods may be used during connection setupand docking session setup. A docking service may provide specificinformation to the ASP so that the ASP can use the underliningmechanisms, including P2P Provision Discovery and P2P Group Formation toset up the connection.

After the ASP session setup for the docking service, WD 4 may triggerthe docking configuration and control protocol to select and configureits PFs/WDNs of interests. The docking service may performs theconnection setup and ASP session setup using one or more of thefollowing methods provided by ASP.

-   -   Docking ConnectSessions Method        -   Example primitive: ConnectSessions(List of(service_mac,            advertisement_id), session_information, network_role)        -   The service seeker (e.g., WD 4) may call the ConnectSessions            Method to initiate the Docking service request to the            discovered service advertiser.        -   The session_information may be a UTF-8 string.    -   Docking ConfirmSession Method    -   Example primitive: ConfirmSession(session_mac, session_id,        confirmed)        -   When the WDC application confirms to accept the            SessionRequest Event, the WDC service may call            ConfirmSession Method with the confirmed set to TRUE.    -   Docking BoundPort Method        -   Example primitive: BoundPort(session_mac, session_id,            ip_address, port, proto)        -   The BoundPort method may be used when the docking service is            deployed over IP.        -   The docking service may use the BoundPort Method to open one            TCP port on the ASP for the docking configuration and            control protocol.        -   The Docking Service may use one of various port values and a            proto value of 6 (TCP), for example.

The following method may be used during docking session teardown.Docking session teardown may be executed using the WFDS ASP. A dockingsession teardown may be trigged by a docking service on either WD 4 orWDC 6. The Docking Session Teardown procedure may trigger the dockingservice to close the ASP session of each individual PF Service betweenthe corresponding WDC and the WD.

-   -   WSB CloseSession Method        -   Example primitive: CloseSession(session_mac, session_id)        -   Once CloseSession is executed, the port that is not            associated with any other open ASP-Sessions may be blocked            again.
